FUEL MIXER FOR INTERNAL-COMBUSTION ENGINES. p

Application filed March 25, 1921.

To all 107mm t may concer/rt:

Be it known that I, GHARLESL. REED, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Fuel Mixers for Internal-CombustionEngines, of which the following is a specification.

The present invention relates to fuel i mixers for internal combustion engines, and. an object thereof is to provideV for mixingthe fuel delivered to an internal combustion engine so that a more effective operation ofthe engine is secured. Another object of the i invention is to provide a simple and inexpensive means .for utilizing the exhaust gases from the explosive engine for the purpose of heating the fuel delivered to the enveine. i b To theseand other ends the invention consists of certain vparts and combinations of parts,all Vof which will be hereinafter described, the novel features being pointed out in the appended claims.,

In the drawings:

Fig. 1 shows a fragment of an explosive engine ofthe type used in the Ford automobile, the present invention being incorporated therein;

Fig. 2 is a fragmentary view partially in section showing the manner in which the exhaust manifold and the intake manifold are associated with the present invention;

Fig. 3 is an enlarged face view with the parts broken away, showing the chambered member;

Fig. 4C is a section on the linel-l, Fig. 3;

Fig. 5 is a detail sectional view showing the manner in which the exhaust manifold connects with the chambered member;

' Fig. 6 isa detail view showing the manner in which the intake manifold connects with the chambered member; Fig. 7 is a detail sectional view of the connection between the chambered member and the member which encloses the intake manifold; and

Fig. 8 is a detail view of another embodiment in which the heating coil is on the in ner side of theA mixing device.

Referring more particularly to the drawings, 1 indicates an enginebody or casing which is of known construction and has four chambers 2, each of whichhas leading thereto, an exhaust valve chamber 3 and an in- Seral No. 455,560.

let valve chamber 4. The adjacent inlet valve chambers 4i have a common inlet opening 5, while the exhaust valve chambers 3 have individual outlet openings 6. The manifold 7 leading from the carburetor, not shown, has two branches as is common, connecting with the inlet openings 5, while the exhaust manifold 8 has four branches as is common, connecting with the exhaust openings 6. These manifolds are held in position as is common, by clamping pieces 9 secured to anchor bolts 10, which are, in 'this lem'lbodiment, longer than the usual anchor o ts.

With the end in view of heating the gases passing from the manifold into the inlet valve chambers and at the same time, effecting a thorough mixture of the constituents of said gases, there is provided preferably between the manifold and the body 1 of the engine, .a mixing device preferably similar to that disclosed in my U. S. Patent No. 1,300,015, granted April 8, 1919, and embodying a plurality of non-moving Itwisted blades llrsecured to each other` in an axial line and each gradually decreasing in width toward its outer end. The mixing device is arranged within a collar or sleeve 12 and preferably is also combined with a spirally formed coil 13 connected by terminals 31 with any vsuitable electric source, such as the batteries of the explosive engine. This coil may be arranged either on the outer side of the mixing device as illustrated in Figs. 3, l and 6, or on the inner side of the mixing device as illustrated at 13a in Fig. 8. .This coil is designed for heating the gas on the starting of the engine and when usedduring the usual running of the motor, it -will heat the gas and effect Ia still furthermixture in combinationwith the mixing device.

Also associated with the sleeve or tubeV 12 which forms a part of the passageway be-y tween the carburetor and the engine is a heating means preferably in the form of a chambered member which receives exhaust gases from the exhaust of the engine. This chambered member, in this instance, is formed by two sheets of material 141, pressed in opposite directions to provide a chambei' 15 between them, the edges of the sheets being welded or otherwise secured together at 16. The tube or sleeving 12 connects the opposite walls of the chamber and is provided with two ianges 12a which have the dual function of separating the walls of the chambered member and also of conducting heat from the chambered member to the sleeve 12. The position of this sleeve 12 is, in this instance substantially midway between the ends of the chamber which is of elongated form, passageway being pro vided about the sleeve from one end of the chamber to the other. One chambered member is provided for each inletcpening 5 and the two adjacent exhaust openings 6.

The chambered member also has two sleeves.

or tubes 17 connecting opposite walls thereof on' opposite sides of the sleeve 12 and forming parts of the two exhaust passageways, establishing connection between the exhaust openings V6 and Athe exhaust manii fold 8. Each of these sleeves or tubes 17 is provided with two surrounding flanges 18 and serving to space said walls apart. s

With the end in view of providing communication between the exhaust passageways and the chamber 15, the sleeves 17 are prof vided with lateral ports 19 between the ianges 18, these ports opening to the chamber 15, and the chamber 15 being provided with an outlet opening 20. By this arrange-V ment, a circulation is created through the chamber 15 about the sleeve 12 due to the fact that when pressure exists in one of the sleeves 17 a reduction in pressure will take place in the other sleeve, thus causing the exhaust gases to iiowthrough the outlet 20,

which, inorder to maintain a pressure in the chamber. 15, is smaller than the openings or ports 19.

Each chambered member is supported on two of the anchoring studs or pins 10 and toY this end each chamber is provided with openings through which the pins extend,

these openings, inA this instance, being;

, the inlet and exhaust manifolds against the chambered member and the flanges on the sleeves 12 and 17 4prevent the distortion of the walls of the chambered member under the pressure of the clamping devices.

With the purpose in view of heating the intake manifold, there may be provided a chamber. about said manifold connecting with the chambered member 15. This manifold enclosing chamber comprises a back plate 24 arranged in rear of the manifold and a front member 25 secured to the back plate by fastening devices 26. The back plate has an inlet opening formed in a sleeve 27 pressed from such back plate and Y chambers 15.

vportion of the manifold enclosing chamber andis carried by a plate 30 which is secured about the lower portion of the manifold. Packing 31 surrounds Vthe three arms of the manifold so as to prevent the escape of the exhaust gases except ythrough the tubing 29. This tubing also permits the dis-Y charge of the carbon forming'in the mani-` fold enclosing chambeig'kas Vwell as` inthe 'The voperation of the invention will be understood from the foregoing description, but it may be summarized vas follows:

ln starting the engine, the coils 13 are heated from the battery and after the engine has started, the exhaust gases will pass from the exhaust passageways into the chambers 15, thus heating the tubing 12 which will by conduction, heat the bladedmixing dei vice 11. The exhaust gases passing from the chambers 15v through the outlet will then pass into the manifold enclosing cham.-

ber and heat themanifoldand from the` latter will be dischargedto the atmosphere; The circuitous path which theexhaust gases must take, mufles the exhaust sound.V As each chamber 1K5 receives exhaustgases alternatelyV from two ofthe exhaust ports, one

of such ports does; notV retard the flow ofv gas through the chamber while the other is` active. Y i 1. 1 f

From the foregoing it will be sehen that there has been providedan effective means for heating and mixing the gases fed to an explosive engine. which conducts the exhaust gases about a sleeve onl tubular member through which the fuel travels, this tubular member having therein, a mixing device which effectively mixes the gases and iswat the same time heated by the exhaust gases. This result is secured1 in this inst-ance, by a chambered member which is adapted to be Varranged. between the intake and the exhaust mani- MeansV is provided fold for the purpose of conductingV the lexhaust gases about the intake passageway which leads through the chambered member. This chambered member is adapted yfor attachment to the ordinary motorv without making any.` material changes therein. Means is also provided for heating the intake manifold in an effective way from the exhaust gases.
